Experience working in a factory setting. I got to become familiar with working with other engineers, technical jargon, working with contractors, and working with process technicians.

A little more in-depth explanation as to the total process earlier on.
Have dedicated work clothes because everything that you bring into the factory will smell like sugar beets. After a while, you don't notice it, but roommates, friends, significant others, family, they all will.
